“No other branch of civil engineering tolerates this level of system failure. In any other field, if engineers knew that systems would fail catastrophically about 30 times this year and knew when, where, and why that was most likely to happen, they would be required to intervene or shut everything down. And if they didn't, there would be serious professional consequences: firing, fines, loss of license, and, depending on how egregious the infraction, criminal penalties” https://sf.streetsblog.org/2024/03/27/guest-commentary-traffic-engineers-must-put-safety-over-driver-throughput
